TLV320AIC21IPFBRG4 TLV320AIC21CPFBG4 TLV320AIC21CPFBR pdf datasheetDESCRIPTION
The TLV320AIC2x is a low-cost, low-power, highly-integrated, high-performance, dual-voice codec. It features two 16-bit analog-to-digital (A/D) channels and two 16-bit digital-to-analog (D/A) channels, which can be connected to a handset, headset, speaker, microphone, or a subscriber line via a programmable analog crosspoint.The TLV320AIC2x provides high resolution signal conversion from digital-to-analog (D/A) and from analog-to-digital (A/D) using oversampling sigma-delta technology with programmable sampling rate. The TLV320AIC2x implements the smart time division multiplexed serial port (SMARTDM(TM)) . The SMARTDM (R) port is a synchronous 4-wire serial port in TDM format for glue-free interface to TI DSPs (i.e., TMS320C5000 , (R) TMS320C6000 DSP platforms) and microcontrollers. The SMARTDM(TM) supports both continuous data transfer mode and on-the-fly reconfiguration programming mode. The TLV320AIC2x can be gluelessly cascaded to any
SMARTDM-based device to form a multichannel codec, and up to eight TLV320AIC2x codecs can be cascaded to a single serial port. |
